From the Highlights: "Border security has been a mission priority since DHS' inception. Executive Order 13767, issued in 2017, directed DHS to strengthen southern border security. Technology is a critical component for gaining and maintaining operational control of the border. We conducted this audit to assess the effectiveness of CBP [Customs and Border Protection]'s current tools and technologies to support Border Patrol's mission to prevent the illegal entry of noncitizens who may pose threats to national security."
